The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks. We’ve got a solid run of surf coming up, but it’s not all for the faint of heart. The water temp is sitting at a warm 80°, which is pretty much bang on average for this time of year, so no surprises there.
Right out of the gate, we’re into it on Friday the 11th. The main event is Lakey Pipe. It’s a reef break, exposed to the SW, and that’s exactly where the swell is coming from. The combined swell energy is solid, hitting 2185 (moderate to strong), pushing waves around 7 ft. That’s groundswell too, with a period of 16 seconds, which means proper lined-up sets. It’s going to be clean with a light cross-off breeze. This is proper intermediate territory—at this size, beginners will find it a handful. It’s a consistent spot, so you won’t be waiting around, but crowds are likely here.
Through Saturday and Sunday the 12th and 13th, the swell holds firm. Sunday afternoon sees a bit of a jump to 8 ft with the energy climbing to 3725, but there’s a bit more wind on it, still cross-off though. Still clean enough for experienced surfers.
Monday the 14th is a bit more of a mixed bag, with the conditions a little more marginal, but the swell stays in the 6 ft to 7 ft range. Tuesday the 15th and Wednesday the 16th look excellent again, with light winds and clean 6 ft to 7 ft waves. The energy dips a bit mid-week but stays in a strong range.
The standout window? I’d be looking hard at Sunday the 20th and Monday the 21st. On Sunday morning, we get a pulse of 6 ft with a 17-second period, energy of 2490, and light winds. Then Monday serves up 8 ft again with a 15-second period and energy at 2307. The wind is near-glass on Monday afternoon… a light 3 mph cross-off. That’s about as clean as it gets for a spot like this. The swell direction is SW, right in the pocket for Lakey Pipe. For experienced surfers, this is the pick of the fortnight. But remember, at over 7 ft, this is expert-only territory.
The second week keeps pumping. Thursday the 24th through Saturday the 26th of September all show clean conditions with light SE winds and solid swell in the 5 ft to 7 ft range. The 26th has a big pulse of energy—over 2700—with 7 ft and an 18-second period. Again, that’s a powerful, long-period groundswell which will be hitting the reef perfectly.
Overall, it’s a solid, consistent run with no real gaps. The best of it is the 20th through 21st, and then again on the 26th. If you’re an experienced surfer, get on it. Beginners, give this one a miss until the swell drops below 5 ft later in the week.
Stay safe, keep your line, and I’ll see you out there.
Rusty.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
